Both Magdalena and Lucas would like to thank the other participants of the conference for their insightful suggestions, and specially to Randolph Bruno (a.k.a. the best chair ever!), Jan Fidrmuc and Tomasz Mickiewicz. We will work to implement their suggestions. PS: as a bonus, they participated in an open conference organized by the London School of Economics where the key speakers were Dani Rodrik and Sir Paul Collier.
